Resin printers are definitely better for smoothness and detail, but I've stayed clear of them because the resin is a lot more toxic than working with PLA. So, yeah, they are, but they're no where near as I assumed before owning one. Full disclosure (and disclaimer), I am not hugely risk averse, and you should not take anything I'm about to say as absolute truth. Always do your own homework, take every precaution you can, and assume the worst. The MSDS (material safety data sheet) for any given resin is usually available from their website. Every one I've read more or less sums up as "do not drink, wash your hands if you get it on your skin, if it's giving you problems breathing, get some fresh air". I compare it to petrol/gasoline in that both are nasty stuff, but when you use them appropriately, they're totally fine. These days I don't even wear a respirator or gloves when I'm handling resin, and my printer sits about 2' from my face at my desk. Resin printing is messy, and the resin is more expensive, and cleanup/post-processing is a different beast entirely. I don't have pets or children, so I can be a bit more slapdash and take more risks, so that's also worth bearing in mind. Not to plug my channel, but I stream on Twitch every Friday and Saturday. If you're on there and you see me streaming, feel free to pop in and ask me about this sort of thing. I'm totally open to sharing XP with this sort of thing (typically Fridays nights are maker/creative streams): https://go.twitch.tv/talongrayson I have 5 or 6 years of 3D printing experience with FDM/FFF (PLA, I've never found a need for other materials so far) and MSLA (resin) printers, and I can talk about it for days 😂 Link to comment Share on other sites More sharing options...
Erratic1 Posted January 21, 2022 Share Posted January 21, 2022 Friend of mine has a venting setup for his resin printer shunting fumes outside. Link to comment Share on other sites More sharing options...
leeper48 Posted January 21, 2022 Author Share Posted January 21, 2022 I have a similar setup for my Ortur laser engraver. The fumes from cutting plywood were pretty noxious but once I built an enclosure and setup ducting with and inline fan it completely eliminated it.

TalonGrayson Posted January 21, 2022 Share Posted January 21, 2022 The main benefit of venting a resin printer is getting rid of the smell, to be honest. Some resins smell worse than others. I've found that most are inoffensive, but one particular resin stank so much it literally made my eyes water. Link to comment Share on other sites More sharing options...

I'm not an expert on toxic materials and maybe the sources I'm looking at are dated (eg. there are non-toxic resin brands on the market). But a quick google search on resin will say that it is very toxic, should not be handled without gloves, needs proper ventilation, and is extremely damaging to the environment if not disposed of properly. Note that by toxic I don't mean "unpleasant to be around". I'm talking about damage to your skin, particles in your eyes and lungs, etc. Link to comment Share on other sites More sharing options...

I’ll try finer height settings first before getting another printer. I use an automotive primer called Duplicolor primer filler. It's really good for filling in print lines. Spray the model and then you're sanding the primer to the level of the lines, rather than trying to sand down the ridges of the plastic. Link to comment Share on other sites More sharing options...

Uncured resin should never, ever be disposed of in any way whatsoever. Cured resin can be landfilled but not recycled, but isn't an environmental hazard otherwise. I've attached an MSDS for Elegoo ABS-like resin. It's a pretty typical resin, but each resin is slightly different. Like I say, I can't in good conscience tell anyone not use PPE when using resin, but I am certain it's less dangerous than most people think. It's good to be cautious, but it's also good to have all the facts (the MSDS), as well as some anecdotal experience to give context.

TalonGrayson Posted January 22, 2022 Share Posted January 22, 2022 This needs some clean-up and a lick of paint, but I'm pretty happy with how it came out. Only a couple of minor printing defects... I'll probably reprint it tbh Glue for scale Link to comment Share on other sites More sharing options...
